Title: Method for controlling wireless packet transmission
Inventor: HONMA FUMIHIRO
IPC: H04W72/04
Filed: 2001-06-13
Abstract: PROBLEM TO BE SOLVED: To provide a method for controlling wireless packet transmission for a plurality of wireless terminal stations, by which the utilization efficiency of a channel when a wireless base station and the wireless terminal stations use the same channel can be enhanced. SOLUTION: A wireless terminal station with a transmission request generates a random number which is uniformly distributed between 0-N, and starts transmission with a packet selected on the basis of the random number. A wireless terminal station, having no transmission request, generates a random number which is uniformly distributed between 0-N, assumes starting of transmission with a packet selected on the basis of the random number, and monitors a channel.  When a transmission packet from other wireless terminal station is detected, it is discriminated that a random slot setting range is small; while when the transmission packet of the other wireless terminal station is not detected, it is discriminated that a random slot setting range is large; when number of times of discriminating the random slot setting range to be smaller than an optimal value exceeds a threshold, the random number generating range is extended, and when number of times of discriminating the random slot setting range to be greater than the optimal value exceeds a threshold, the random number generating range 0-N is reduced.

IPC: H02K1/27
Filed: 2001-06-20
Abstract: PROBLEM TO BE SOLVED: To provide a brushless DC motor which hardly impairs an output characteristic and surely reduces cogging torque. SOLUTION: A magnetic pole center line J1 is diviated from an effective magnetic pole opening angle center line K1 by an angle of θ4, at the magnetic pole of a permanent magnet 3(S).
